OCZ has customer support forums, some of them dedicated to their SSD productes. It's probably worth a try to ask there: http://www.ocztechnologyforum.com/forum/forum.php intel has something similar (but my impression is that it's less helpful). Here's the link: http://communities.intel.com/community/tech/solidstate Just found two intersting threads there, discussing the durability of intel SSDs: http://communities.intel.com/thread/8118 http://communities.intel.com/thread/8559 Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
